Abstract
Abstract The ritual space of the Sanctuary of Aesculapius in Nora (Sardinia) is the main focus of a recent archaeological campaign led by the Cultural Heritage Department of the University of Padova. A partnership with 3DOM research group (Fondazione Bruno Kessler, Trento) has offered new opportunities for a digital investigation of the site. The aim of the project is to map and visualize the sanctuary with methodologies enabling different users to engage with the site in new ways. They offer different web tools for exploring, understanding and interacting with the site, by focusing on 3D modelling, semantic enrichment and the contextualization of digital records. The entire site of Nora has been surveyed by a drone, which produced a digital model of the peninsula. A number of outputs have been used for different scales of visualization and a range of purposes: an open source multi-resolution web renderer is used to navigate the point cloud, labelled using a system of bounding boxes. At the same time it provides access to a 2.5D model of each building. Plugins in QGIS are used to produce extrusions of any mapped feature, gaining height values from the point cloud, and attributes from the shapefile. Photogrammetric models of single ritual artifacts can be located in their own context and be displayed using 3D web renderers.

Summary
The world of archaeology has always been receptive to investigating and applying new technologies. It is dealing with products that are very effective in visualizing and querying data, such as 3D models from photogrammetry and increasingly efficient Geographic Information Systems (GIS), whose connection to the Web makes them constantly online and accessible They can be considered a resource for research, but the even harder mission of cultural dissemination, the transformation of a scientific input into historical knowledge, context and value. This work is licensed under the Creative Commons are a clear sign of a community acknowledging Digital Humanities as a part of itself This contribution is intended to reach specific solutions for the analysis of the ritual complex of the Sanctuary of Aesculapius in Nora (Sardinia, Italy), as well as to explore opportunities for managing new virtual models in order to make them meaningful and informative about the complexity of the reality. The results provide a range of models for different points of view that are suitable for future developments, especially for analysis and dissemination purposes
